Hi @abefqy,
thank you very much for sending the files.
The files showed error 1726 which meant “The remote procedure call failed.” Please try the following:
Option #1.
In Task Manager, Services tab, the service RpcSs (Description: Remote Procedure Call (RPC)) Status should be “Running”. If not, please start it.
Try to install spacedesk.
Option #2 (if Option #1 did not work)
Run a system file checker.
Open the command prompt as admin and type sfc /scannow.
When the scan has finished, try to install spacedesk.
Looking forward to your feedback.
